No.17/664,643, filed May 23, 2022, which claims priority under 35 U.S.C. §119(e) to U.S. Provisional Application No. 63/202,009, filed on May 22,2021. The disclosures of these prior applications are considered part ofthe disclosure of this application and are hereby incorporated byreference in their entirety.

FIELD

The present disclosure relates to footwear, generally an article ofathletic footwear, and more particularly to sole arrangement for articleof athletic footwear.

BACKGROUND

This section provides background information for the disclosurepresented herein without being necessarily prior art. This sectionfurther illustrates the inventive entity's observations mixed with theinventive entity's novel and inventive functional steps that precedesthe detailed description of the invention.

Footwear articles provide a comfort and protective layer, sole structureor sole arrangement that separates a foot from engaging a ground, wherebarefoot contact with the ground, which may be of a certain groundsurface, may not be ideal. Footwear articles traditionally furtherinclude an upper that secures the foot to the sole arrangement as tokeep a foot on top of the sole arrangement. Footwear articles, moreparticularly athletic footwear articles, are thicker in the solearrangement under a heel and a surrounding area under the heel andthereby generally provide more cushioning for heel contact, and they arethinner in the sole arrangement under a ball of the foot and asurrounding area under the ball of the foot as compared to a thicknessof the sole arrangement under the heel and the surrounding area underthe heel and thereby provide less cushioning for forefoot contact. Thistraditional sole arrangement further places the heel of the foot at araised position relative to an even surface as compared to the forefootwhen the foot is placed on top of the sole arrangement and the solearrangement is placed on the even surface.

SUMMARY

Footwear sole arrangements traditionally include a sole structure of oneor more layers. At least one of the one or more layers may include atleast one midsole layer that provides foot support and cushioning forgradient weight pressure that comprises a rolling pressure or directsemi-downward pressure. This pressure is generally created by a footwearwearer that is walking, running, exercising on a spot or any otheractivity. The midsole may therefore be compressed and decompressed atmultiple or variable rates with different and variable densitiesdepending on a footwear wearer's weight and a speed of movement. Themidsole may undergo different types of pressure based on a position oran angle of the footwear wearer's strike and contact with a ground, orboth, a position or an angle of the footwear's takeoff and departurefrom the ground, or both, movement or running form of the footwearwearer, or a combination thereof, and other factors and scenarios.

The sole arrangement, including the midsole, may be constructed frommultiple components, materials, layers or a combination thereof, whichmay result in a sole arrangement that has various physical propertiesthroughout the sole arrangement at different positions, such as a softercushioning at a first position of the sole arrangement and a hardercushioning at a second position of the sole arrangement. A choice ofcomponent of certain material for different parts, objects, sub-layers,or layers at different positions of the sole arrangement depends on thepurpose that the component of certain material is intended to serve,such as softness, compression rate, decompression rate andresponsiveness of the component of certain material in a certainenvironment when it comes under gradient loads over a certain groundsurface.

The present invention relates in part to sole arrangements and upperarrangements for articles of footwear that incorporate a gradientcushioning gain. A sole arrangement comprising at least one layer ofcushioning, wherein the at least one layer of cushioning of the solearrangement has a first thickness value in a posterior area of the solearrangement and a second thickness value in an anterior area of the solearrangement. The second thickness, which is a thickness in the anteriorarea of the sole arrangement, is larger than the first thickness, whichis a thickness in the posterior area of the sole arrangement. Theinventive sole arrangement as described herein and illustrated in thedrawings eliminates or reduces an intrusive heel sole cushioning thatinterferes with a midfoot or forefoot strike of a foot on a surface andfurther improves the midfoot or forefoot strike of the foot by elevatingthe forefoot area and/or midfoot area through raising or increasing theforefoot sole cushioning thickness, depth or height to a thicker, largeror higher thickness, depth or height as compared to a hindfoot or healarea sole cushioning thickness, depth or height of the sole arrangementand thereby encouraging and improving a biomechanical ability of themidfoot or forefoot to come in contact with the ground or surface first.

A transition from the posterior area of the sole arrangement, where aheel of the foot would proximately sit on top of, to the anterior areaof the sole arrangement, where a ball of the foot would proximately siton top of, results in a gradient gain in sole thickness. The transitionfrom the posterior area of the sole arrangement to the anterior area ofthe sole arrangement may be at a smaller rate at one point in the solearrangement and at a larger rate at another point in the solearrangement. The transition of the gradient gain in sole depth, heightor thickness value may provide a smooth initial and continued groundengagement of the sole arrangement at and around the anterior area ofthe sole arrangement. Optionally, additionally or interchangeably, thetransition of the gradient gain in sole thickness, depth or height valuemay provide a smooth initial and continued ground engagement of the solearrangement at and around an intermediate area of the sole arrangement.

The first depth transition rate is calculated by dividingthe maximum intermediate depth value with the maximum anterior depthvalue (first depth transition rate=maximum intermediate depthvalue/maximum anterior depth value).

In an exemplaryembodiment, the second forefoot gain value may be larger or smaller thanthe first forefoot gain value by a ratio between 0% to 25% of the secondforefoot gain value. In another exemplary embodiment, if the secondforefoot gain value has a value of 2.5 mm then the first forefoot gainvalue has a value between 1.875 mm (i.e., 25% smaller than the secondforefoot gain value) and 3.125 mm (i.e., 25% larger than the secondforefoot gain value). Therefore, the main forefoot gain value, for thisexemplary embodiment, is between 4.375 mm and 5.625 mm.

The second forefoot gain ratio being calculated by dividing thesecond forefoot gain value by the main forefoot gain value (secondforefoot gain ratio=second forefoot gain value/main forefoot gainvalue). Furthermore, the sole arrangement comprising a first forefootgain ratio, wherein the first forefoot gain ratio depicting a ratiobetween the first forefoot gain value over the main forefoot gain value.The second forefoot gain ratio being calculated by dividing the firstforefoot gain value by the main forefoot gain value (first forefoot gainratio=first forefoot gain value/main forefoot gain value).

In some implementations, the second forefoot gain ratio is within apredetermined range of the first forefoot gain ratio. In an exemplaryembodiment, the second forefoot gain ratio may be larger or smaller thanthe first forefoot gain ratio by a ratio between 0 to 30 percentagepoints or 0% to 30% in view of a depth gain difference over the mainforefoot gain value, wherein the depth gain difference is an absolutedifference between the second forefoot gain value and the first forefootgain value. In another exemplary embodiment, if the second forefoot gainratio has a ratio of 65 percentage points or 65%, then the firstforefoot gain ratio has a ratio of 35 percentage points or 35%, or viceversa.
